Dayton, Ohio in the context of "Polonium"

Ohio (/oʊˈhaɪ.oʊ/ oh-HY-oh) is a state in the Midwestern region of the United States. It borders Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Of the 50 U.S. states, it is the 34th-largest by area. With a population of nearly 11.9 million, Ohio is the seventh-most populous and tenth-most densely populated state. Its capital and most populous city is Columbus, with other major metropolitan centers including Cleveland and Cincinnati, as well as Dayton, Akron, and Toledo. Ohio is nicknamed the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes".

Ohio derives its name from the Ohio River that forms its southern border, which, in turn, originated from the Seneca word ohiːyo', meaning "good river", "great river", or "large creek". The state was home to several ancient indigenous civilizations, with humans present as early as 10,000 BC. It arose from the lands west of the Appalachian Mountains that were contested by various native tribes and European colonists from the 17th century through the Northwest Indian Wars of the late 18th century. Ohio was partitioned from the Northwest Territory, the first frontier of the new United States, becoming the 17th state admitted to the Union on March 1, 1803, and the first under the Northwest Ordinance. It was the first post-colonial free state admitted to the union and became one of the earliest and most influential industrial powerhouses during the 20th century.

The General Framework Agreement for Peace in Bosnia and Herzegovina, also known as the Dayton Agreement or the Dayton Accords (Serbo-Croatian: Dejtonski mirovni sporazum / Дејтонски мировни споразум), and colloquially known as the Dayton (Bosnian: Dejton; Serbian: Дејтон / Dejton), is the peace agreement ending the three-and-a-half-year-long Bosnian War, an armed conflict part of the larger Yugoslav Wars. It was signed on 21 November 1995 in Dayton, Ohio, United States, at the Wright-Patterson Air Force Base. It was re-signed ceremonially in Paris, France on 14 December 1995.

The warring parties agreed to peace and to a single sovereign state known as Bosnia and Herzegovina composed of two parts: the largely Serb-populated Republika Srpska and mainly Croat-Bosniak-populated Federation of Bosnia and Herzegovina. Bosnia and Herzegovina entered into the related arms control treaty, the Florence Agreement, in 1996 under the Accords. The Dayton followed the Washington Agreement, signed the year prior, in collective efforts to delineate the country's geography.

The U.S. Air Force Test Pilot School (USAF TPS) is the United States Air Force's advanced flight training school that trains experimental test pilots, flight test engineers, and flight test navigators to carry out tests and evaluations of new aerospace weapon systems and also other aircraft. This school was established on 9 September 1944 as the Flight Test Training Unit at Wright-Patterson Air Force Base (AFB) in Dayton, Ohio. On 4 February 1951, the school was moved to Edwards Air Force Base in the Mojave Desert of Southern California, which offered uncongested skies, usually superb flying weather, and a lower risk that a crash would threaten people or buildings.

The TPS was created to formalize and standardize test pilot training, reduce the high accident rate during the 1940s, and increase the number of productive test flights. In response to the increasing complexity of aircraft and their electronic systems, the school added training programs for flight test engineers and flight test navigators. Between 1962 and 1972, the test pilot school included astronaut training for armed forces test pilots, but these classes were dropped when the U.S. Air Force crewed spaceflight program was suspended. Class sizes have been uniformly quite small, with recent classes having about twenty students. The school is a component of the 412th Test Wing of the Air Force Materiel Command.

Interstate 75 (I-75) is a major north–south Interstate Highway in the Great Lakes and Southeastern regions of the United States. As with most Interstates that end in 5, it is a major cross-country, north–south route at a length of 1,786.47 miles (2,875.04 km), traveling from State Road 826 (SR 826, Palmetto Expressway) and SR 924 (Gratigny Parkway) on the Hialeah–Miami Lakes border (a few miles northwest of Miami, Florida), to Sault Ste. Marie, Michigan, at the Canada–United States border. It is the second-longest north–south Interstate Highway (after I-95) and the seventh-longest Interstate Highway overall.

I-75 passes through six different states. The highway runs the length of the Florida peninsula from the Miami area and up the Gulf Coast through Tampa. Farther north in Georgia, I-75 continues on through Macon and Atlanta before running through Chattanooga and Knoxville and the Cumberland Mountains in Tennessee. I-75 crosses Kentucky, passing through Lexington before crossing the Ohio River into Cincinnati, Ohio. In Ohio, the highway runs up the western side through Dayton and Lima before crossing into Michigan north of Toledo. I-75 runs northeasterly along the Lake Erie shoreline and Detroit River into the city of Detroit before turning northwesterly to Flint and northward to the Mackinac Bridge where the freeway crosses the strait between Lakes Huron and Michigan. Farther north, I-75 approaches the Canadian border at Sault Ste. Marie, downriver from Lake Superior, 1,786.5 miles (2,875.1 km) from its origins near the subtropical Atlantic Ocean.

Wright-Patterson Air Force Base (WPAFB) (IATA: FFO, ICAO: KFFO, FAA LID: FFO) is a United States Air Force base and census-designated place just east of Dayton, Ohio, in Greene and Montgomery counties. It includes both Wright and Patterson Fields, which were originally Wilbur Wright Field and Fairfield Aviation General Supply Depot. Patterson Field is about 16 kilometres (10 mi) northeast of Dayton; Wright Field is about 8.0 kilometres (5 mi) northeast of Dayton.

The host unit at Wright-Patterson AFB is the 88th Air Base Wing (88 ABW), assigned to the Air Force Life Cycle Management Center and Air Force Materiel Command. The 88 ABW operates the airfield, maintains all infrastructure and provides security, communications, medical, legal, personnel, contracting, finance, transportation, air traffic control, weather forecasting, public affairs, recreation and chaplain services for more than 60 associate units. The Air Force's National Air and Space Intelligence Center (NASIC) and the Space Force's National Space Intelligence Center (NSIC) are also garrisoned there and are the intelligence community's primary organizations for strategic air and space threat analysis.
